#22642 [NEW]: After saving a session var in a var, nulling the session var clears the 2nd var

From: dave at orangechicken dot com Operating system: Linux / Apache 1.3.27 PHP version: 4.3.1 PHP Bug Type: Session related Bug description: After saving a session var in a var, nulling the session var clears the 2nd var OK, the summary was too short to concisely enter what I mean. Here's the real version: After assigning a stored $_SESSION var to another variable, assigning null to the $_SESSION var clears the other variable too. This worked before 4.3.1 (possibly occurred in 4.3.0 - we skipped from 4.2.7 to 4.3.1). Here's a snippet where the problem occurs. $_SESSION[ 'login_redirect' ] contains the value 'checkout.php'. ================================ $redirect = $_SESSION[ 'login_redirect' ]; echo $redirect; // outputs checkout.php $_SESSION[ 'login_redirect' ] = null; echo $redirect; // outputs <nothing> ================================ Here's the configure string './configure' '--with-apxs=/usr/local/apache/bin/apxs' '--with-xml' '--enable-bcmath' '--enable-calendar' '--with-curl' '--enable-ftp' '--with-gd' '--with-jpeg-dir=/usr/local' '--with-png-dir=/usr' '--with-xpm-dir=/usr/X11R6' '--with-imap' '--with-imap-ssl' '--with-kerberos' '--with-mcrypt' '--enable-magic-quotes' '--with-mysql' '--with-pear' '--enable-xslt' '--with-xslt-sablot' '--enable-sockets' '--enable-track-vars' '--with-ttf' '--with-freetype-dir=/usr' '--enable-gd-native-ttf' '--enable-versioning' '--with-zlib' -- Edit bug report at http://bugs.php.net/?id=22642&edit=1 -- Try a CVS snapshot: http://bugs.php.net/fix.php?id=22642&r=trysnapshot Fixed in CVS: http://bugs.php.net/fix.php?id=22642&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=22642&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=22642&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=22642&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=22642&r=support Expected behavior: http://bugs.php.net/fix.php?id=22642&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=22642&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=22642&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=22642&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=22642&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=22642&r=dst IIS Stability: http://bugs.php.net/fix.php?id=22642&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=22642&r=gnused
